Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.
Aloha Paragraphs
The looping satellite imagery above shows high
cirrus clouds moving northeast
Light trade winds with afternoon upcountry
clouds and showers here and there, along with
some windward showers locally…mostly during
the night and early morning hours ~~~ our winds
will turn very light early next week
~~~ Hawaii Weather Narrative ~~~
The generally light trade winds will remain active this week…although will fade away later this weekend into early next week. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find a near 1027 millibar high pressure system to the northeast. At the same time, there’s low pressure troughs not far to the northeast of Hawaii. Meanwhile, there’s many low pressure systems to the north and northwest. These light trade winds, locally a bit stronger at times, will remain in place through Saturday..then become lighter Sunday into early next week.
Satellite imagery shows partly cloudy skies over the islands…with high cirrus clouds being carried over us from the southwest. Looking at this larger looping satellite image, it shows a large area of thunderstorms well offshore to the southwest of Hawaii…with the cirrus tops being transported over our area. These high clouds will dim and filter our Hawaiian sunshine at times, and bring locally colorful sunset and sunrise colors. The light winds over our region, in conjunction with the daytime heating of the islands, will prompt afternoon clouds and some showers locally over our leeward upcountry slopes. The trade winds, despite being on the light side, will bring the windward sides a few incoming showers too. In general, rainfall will remain on the light side over the next several days. Here’s the looping radar, showing just a few showers moving across our island chain, which will continue in an off and on manner. I’ll be back with more updates on all of the above and below, I hope you have a great Tuesday night wherever you happen to be spending it! Aloha for now…Glenn.
World-wide tropical cyclone activity:
Atlantic Ocean: There are no active tropical cyclones
1.) A broad area of low pressure is located about 600 miles west-southwest of the Cape Verde Islands, with the associated shower and thunderstorm activity remaining disorganized. While tropical cyclone formation is not anticipated today, environmental conditions could become somewhat more favorable for development by later in the week while the low moves toward the west-northwest and northwest at about 15 mph over the open Atlantic.
Here's what the computer models are showing...for what is being
referred to as Invest 91L.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...high...70 percent
2.) Disorganized cloudiness and showers over the Bahamas and the adjacent Atlantic are associated with a weak surface trough interacting with an upper-level low. Development, if any, of this system is expected to be very slow to occur while it moves generally westward at 5 to 10 mph during the next few days.
* Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent.
Here’s a satellite image of the Atlantic Ocean
Caribbean Sea: There are no active tropical cyclones
Gulf of Mexico: There are no active tropical cyclones
Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico.

Eastern Pacific: Tropical Storm 15E (Odile) is now active in the northeast Pacific, located about 220 miles south-southwest of Lazaro Cardenas, Mexico…with sustained winds of near 40 mph. Here’s a graphical track map…along with a satellite image. Here’s what the computer models are showing for this strengthening tropical storm.
1.) An area of low pressure located about 800 miles south-southwest of the southern tip of the Baja California peninsula is showing signs of organization. This low could become a tropical depression during the next day or two before upper-level winds become unfavorable. This system is expected to move slowly northward during the next couple of days and then turn eastward after that.
* Formation chance through 48 hours…high…60 percent
* Formation chance through 5 days…high…60 percent
2.) A broad area of low pressure located about 1300 miles southwest of
the southern tip of the Baja California peninsula is producing
disorganized showers and thunderstorms. Some development of this
system is possible during the next few days while it moves slowly
northward and then northeastward.
* Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent.
Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.
Central Pacific: There are no active tropical cyclones
1.) A surface trough about 550 miles south-southeast of Honolulu Hawaii produced pulsing showers and thunderstorms. As this disturbance moves toward the west at 5 to 10 mph during the next couple of days, environmental conditions are forecast to support gradual development.
* Formation chance through 48 hours, low…near…10 percent.

Northwest Pacific Ocean: here are no active tropical cyclones
South Pacific Ocean: There are no active tropical cyclones
North and South Indian Oceans: There are no active tropical cyclones

Interesting: Greenhouse gases hit new record– The World Meteorological Organization (WMO) has reported that the amounts of atmospheric greenhouse gases reached a new high in 2013, driven by rapidly rising levels of carbon dioxide.
The news is consistent with trends in fossil fuel consumption. But what comes as more of a surprise is the WMO’s revelation that the current rate of ocean acidification, which greenhouse gases (GHGs) help to cause, appears unprecedented in at least the last 300 million years.
“We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels”, said the WMO’s secretary-general, Michel Jarraud.
“The Greenhouse Gas Bulletin shows that, far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years. We are running out of time. The laws of physics are non-negotiable.”
A 34% increase in radiative forcing from 1990 – 2013
The details of growing GHG levels are in the annual Greenhouse Gas Bulletin, published by the WMO – the United Nations specialist agency that plays a leading role in international efforts to monitor and protect the environment.
The Bulletin reports on atmospheric concentrations – not emissions – of greenhouse gases. Emissions are what go into the atmosphere, while concentrations are what stay there after the complex system of interactions between the atmosphere, biosphere (the entire global ecological system) and the oceans.
The Bulletin shows that between 1990 and 2013 there was a 34% increase in radiative forcing – the warming effect on our climate – because of long-lived greenhouse gases such as carbon dioxide (CO2), methane and nitrous oxide.
About a quarter of total emissions are taken up by the oceans and another quarter by the biosphere, cutting levels of atmospheric CO2.
In 2013, the atmospheric concentration of CO2 was 142% higher than before the Industrial Revolution started, in about 1750. Concentrations of methane and nitrous oxide had risen by 253% and 121% respectively.
